Have you used the Obamacare or some kind of children's health insurance? Maybe food stamps? Well, the government could use this against you.

After its battle against undocumented immigration and after its modification of procedures within Citizenship and Immigration Services (USCIS), the government plans to reduce the number of immigrants with "legal" status in the country, according to what sources close to the measure told NBC News.

The strategy is part of the hidden agenda of Stephen Miller, the presidential adviser and architect of the end of DACA. Miller has now designed a presidential order that will not need approval from Congress, and which contemplates that "immigrants living legally in the U.S. who have ever used or whose household members have ever used Obamacare, children’s health insurance, food stamps and other benefits could be hindered from obtaining legal status in the U.S.," according to the measure’s draft.

This would be one of the most important changes in the country's legal immigration system in decades and could affect "more than 20 million immigrants."

Its initial version has already been sent to the Office of Management and Budget of the White House, according to the sources, a step prior to the approval of the decision in the federal register.

A spokeswoman for the Department of Homeland Security told NBC that "the administration is committed to enforcing existing immigration law, which is clearly intended to protect the American taxpayer by ensuring that foreign nationals seeking to enter or remain in the U.S. are self-sufficient."
